Gameplay
The game is a racing video game. The player directs the car using the D-pad, accelerating with A and braking with B. The gauges, speed, and several other things can be seen at the bottom of the screen. Turbo boosts can be used by the player when necessary, but must be refuelled when empty. Hazards such as signposts and other cars must be avoided. Qualifying is held prior to each race, but is difficult because only one lap is given.
Due to the limitations of the NES, curves appear to come out of nowhere, making turning unusually difficult.
